.'IMPROVED FEEDING APPARATUS-FOR NAIL-MACHINES.

Specification forming part of Letters Patent No. 10 l,496. dated April5,1870.

To all whom it may concern:

Beit known that I, JAMES NOLAN, of OX- pford, county of Warren, andState of New Jersey, have invented a new and useful Im through the linex x, Fig. l.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of theself-feeders of nail-ina chines, to prevent them from being brokenshould anything get beneath the barrel or get out of order; and itconsists in so constructing the feeder that the barrel niay yield shouldanything get beneath the barrel, and in the construction of the deviceby which this is accomplished, as hereinafter more fully described.

A is the bed of the machine.

B is the frame that supports the bed-knife O.

D is a bracket adjnstably attached to the bed A by screws.

E is a bracket adjustably attached to the bracket D by screws. Thescrews that fasten the brackets D'and E pass through slots in saidbrackets, so that the brackets may be adjusted in different directions.

F is a bolt or center-pin, that passes through the bracket E, and issecured to said bracket by two nuts, which are adjustable by the screwG.

H is the revolving barrel that receives and holds the nail-plate whileit is being out, and which revolves in a journal-box attached to theupper end of the arm I, which arm thus supports the said revolvingbarrel H. Upon `the lower end of the arm I is formed a boss,

J, through which the bolt or. center pin F passes, and which rides uponthe said bolt or pin.

K is a slot or opening in the boss J, `which allows it to rise andadjust itself, in case anything gets under the revolving barrel H,between it and the knife C, or gets out of order.

L is a' bar letinto the boss J, and which crosses the slot or opening K,to prevent the arm I J from slipping off the bolt or pin F when therevolving barrel H is thrown back to grind the machine.

M is a connecting-rod worked by a gear-A wheel on' the spindle of thenail-machine, (not shown in the drawings,) and attached to a pin y uponthe journal-box in which the barrel H l. A supporting-arm, I J, for a:nail-platev feeder, vibrating on a pin, F, and having a radial slot, K,to allow the barrel H to rise when anything becomes interposed betweenit and the table, all as set forth.

2. The combination of vibrating arm I J, slotted, as shown, and aspring-rod, M, formed in two parts, as set forth, with the barrel H, allconstructed and arranged as and for the purpose specified.

JAMES NOLAN.
